We had a whirlpool dishwasher model GU1200XTLS installed in our new
house. For the most part it seems to work fine but when we open the
door next day, we see tiny puddles of water on the floor of unit as
well as water droplets on the inside of door. Hence I watched it
during a dry cycle and didn't see any steam come out through the vent
holes at top left side of door. While it was drying, I opened the
door, there was plenty of heat and steam was swirling around inside.
We called whirlpool and they sent a service tech and he checked
everything and said it is quite normal to see droplets after it is
done; he then left. The dishes do seem dry if you leave it overnight
but this is the first machine I am seeing water puddles in even after
heat drying. There is no fan in the unit to vent out steam. I guess it
is just natural convection. Could this be defective in some ways?
This was a top of the line model. Are there models (maytag or
whirlpool) that have vent fans?

thanks
